To a, whom it may conlcern:

Be it known that I, WILLIAM WHITE, a eiti zen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful'Improvements in Side Bearings for Railway- Cars, of which the following is a speeification. 7' Y My inventionrelates to side bearings, and has for its object to provide an efficient side bearing in which provision is made for the yielding movement of parts of the bearing and for positively guiding the parts of the bearing in their, movement.

In the accompanying drawin s, Figure 1 is an end-elevation of a portion 0 a car-frame, partly in section,. showing the truck and Ody-bolsters with my improved side bearing thereon. on the line 2 of Fig. 1. Fig. 3 is a transverse section on the line 3' of Fig. 2.

My im roved side'bear-ing comprises the odymember a, having an inclined upper i'a'ce a adapted for connection to the incl'ned, portion. of the body portion by any suitable connecting means passed through the openingsli'. This upper member hasalso flanges. (1 forming a box-like" portion on its'under side, and is previded Wlth'fl series of teeth a on its bearing- -ace-. The lower or'truck member of the side hearing 1) is provided with flanges b iorminga box-like portion. tion is mounted a bearing member I), having on its bearing-face a series of teeth b corresponding to the teeth a of the upper member. Between the upper and lower members is a teo thed roller 0', the teeth of which engage the teeth'of the upper and lower bearing members. This roller is held in position and guided in itsmovements by the flanges on the upper and lower members. The lower bearing portion 17, of' the truck member is.

yieldingly supported by the spring 'b which normally holds the bearing This spring permits a slight yielding of the bearing portion body.

lit will be seen that while the weight is not Fig. 2 is a longitudinal section Within this box-like porportion up in enw normally carried b theside bearings I still have provided aside bearing in which the parts are normallyin contact,- inwhich they are positively-guided in their movements, and in which there is a yielding to 'com ell-- sate-for the movements of the car-body om .one side to the other.

'Iclaim- 1. A side bearing comprisin upper and lower bearing members, a circu ar roller interposed between them, and positive means for compelling the roller to travel upon its bearings to correspond with the relative -movement of the car truck and body.

' 2. A side bearing v comprising an upper member having, a toothed bearing-face, a lower member having 'a correspondinglytoothed bearing-face, and a t'oothed' roller interposed between the upper and lower members and engaging bot the toothed bearing-faces.

3. A side bearing comprising 7 an upper member having a. toothed bearing-face, a

'lower member having a correspondinglytoothed bearing-face, a toothed roller interposed between the upper and lower members lower member..

4. A side bearing having an upper or body member comprising a ear' -face and flanges surrounding the bearingace,'a lower or truck'member oomp'rising'a boxlike portion, a bearing portion therein, means for yieldingly supporting the bearing portion,

and a roller interposed between the upper and lower members.

5. A side bearing having an upper or body member comprising atoothed bearing-face and flanges surrounding the bearing-face, a lower or truck member comprising a box-like portion, a toothed bearing portion therein, means for yieldin 1y supporting the bearing portion, and a rol er interposed between the upper and lower members.
